Influence of Emulsifiers on Acrylate Latex Blends

Abstract

The poly(methyl methacrylate/butyl acrylate/acrylic acid) [P(MMA/BA/AA)] and poly (styrene/ butyl acrylate/acrylic acid) [P(St/BA/AA)] latexes were synthesized using the emulsifier octylphenol polyoxyethylene(10) ether (OP-10) and ammonium sulfate allyloxy nonylphenoxy poly(ethyleneoxy)(10) ether(DNS-86). The optimum amount of OP-10 and DNS-86 was 1.5% and 2.5% respectively. The P(MMA/BA/AA) and P(St/BA/AA) latex containing 1.5% OP-10 or 2.5% DNS-86 were blended pairwise. The performances of latex blends and parent latexes as a function of emulsifiers content in parent latexes were determined. The results indicated that the stability of latex blends is favorable, and particle size distribution was more uniform and thermal stability was improved after blending.

UV-Curing PUA Ink with Polymerizable Surfactant-Enhanced MXene for Fabricating a Durable Conductive Coating on the Cotton Surface

“…In the peeling measurement, the pressure-sensitive adhesive tape was pressed to the coating and quickly peeled off at a 180° angle, recording its resistance value every 10 peeling tests. The electrical resistance values before ( R 0 ) and after ( R ) various treatments were employed to determine the resistance variation (Δ R / R 0 ) of the conductive coatings normalΔ R / R 0 = R / R 0 − 1 The wet durability of the conductive coating on the fabric was verified by exposing the printed fabric to 100 mL of deionized water, seawater, NaOH (0.1 wt %), HCl (1 wt %), or detergent (5 g/L) for 10 h at room temperature. The fabric was taken out and rinsed with deionized water every 1 h and then totally dried.…”

Preparation and Characterization of Novel Acrylic Polymer Latex Using Novel Emulsifiers

“…Emulsion polymerization involves dispersion of a relatively water-insoluble monomer (e.g. BA and MMA) in water at the reaction temperature, initiated the persulfate initiator solution with the aid of surfactants [8]. In the system of the emulsion polymerization, the anionic surfactant and non-ionic surfactant are often used as emulsifiers to stabilize the polymer latexes.…”
